Rep. Jim Renacci (R) – Ohio

Rep. John Boehner speaks to the crowd at a rally for Jim Renacci, right, in Canton, Ohio, in this 2010 file photo. Represenative Renacci has one of the most diverse portfolios in Congress, with investments ranging from fast food chains to stake in a minor league baseball team.

The first-term Ohioan's portfolio is one of the most diverse in Congress. Renacci reports having significant investments in fast-food chains, consumer electronics companies, drugmakers and oil giants.

Renacci has a stake in the Lancaster, Calif.-based minor league baseball team, the JetHawks, worth $100,000 to $250,000 and loaned the Westerville, Ohio, Gordy's Bar and Grill at least $250,000 in 2010. An investment in a Harley-Davidson dealership dropped in value from at least $500,000 in 2010 to about $4,400 in 2011.

Renacci is one of a handful of members of Congress who opted to disclose the exact value of many assets instead of reporting them within broad ranges. He listed $26,000 in Lululemon Athletica, $89,000 in McDonald's and $281,000 in Chevron stocks, among hundreds of financial holdings.

What determines the lawmakers who make the list? Rankings are based on minimum net worth based on assets and liabilities that are cited in broad ranges, so the actual net worth of each representative is not precise.

Roll Call determines net worth by consulting the annual financial disclosure reports from all House and Senate lawmakers, and for each one, subtracts the total minimum value of all liabilities from the total minimum value of their assets.

These disclosures can include assets and liabilities, loans and credit card debt, stock holdings, rental properties, mortgages (reported for the first time this year) and more, but other factors like the values of personal properties and retirement savings are not counted in their assets.
